|L-12 Electra Junior|
|An Electra Junior in Casablanca|
|Maiden flight||27 June 1936|
|Developed from||Lockheed L-10 Electra|
|Variants||Lockheed L-14 Super Electra|
The Lockheed 12 Electra Junior was an eight-seat, six passenger all-metal transport designed for use by smaller airlines and private owners.
Design and Development
British Airways Ltd. ordered two Electra Juniors in 1939. Although ostensibly acquired for civilian purposes, these aircraft were modified for aerial photography and used by Sidney Cotton to track Axis military activity on the eve of World War II.
A modified Electra Junior was used by the NACA as a testbed for "hotwing" deicing technology.
A total of 130 Electra Juniors were built. At the time of Pearl Harbor this aircraft had outsold the competing Beech 18 by 2-1, and Lockheed had over two dozen unfilled orders. In order to concentrate on more vital and advanced wartime aircraft, Lockheed turned the unfilled orders over to Beechcraft, who eventually built many thousands of their Model 18.

An Electra Junior appeared in the film Casablanca. Wartime security precautions prevented shooting at an airport at night, so a cardboard cutout stood in for a real airplane in many shots.
